Small comment about the Netflix support on Linux, it's not so straightforward to make it work. This is what you need:

compatible widevine libraries (see /usr/lib/x86_64-linux-gnu/opera-beta/resources/widevine_config.json for search paths, version 48.x). I'm pretty sure some distros have a separate package for it with some custom installation dir, please let me know about that in comment

ffmpeg with h264 support (e.g. chromium-codecs-ffmpeg-extra version 48.x)

fake user agent to Chromium (--user-agent command line switch)

This version 48 is determined by chromium version our product is based on, major version mismatches sometimes work, but no guarantee.

In my opinion at least for now it's not worth the effort. Better just use Google Chrome for Netflix.

The newest release of Opera beta 33.0.1990.35 is now able to detect whether the chromium-codecs-ffmpeg-extra package is installed. When it is installed Opera can use it to provide support for some proprietary codecs for media elements, including H264 and MP3.

Yes of course you can create symbolic link instead of the whole copying and renaming but either way you will have to change that symlink when Opera Stable 32 releases to libffmpeg.so.32 and with every new version.

I really hope that Opera developers resolve this bug which I already reported to them a couple days ago.

I've found much simpler workaround than that guide which by the way is totally innacurate because there is no third_party/ffmpeg directory in chromium source code. At least not in Chrome/44.0.2403.107 (Opera Stable) and Chrome/45.0.2450.0 (Opera Developer) even master branch doesn't have that directory.

First you need to either install or download chromium-codecs-ffmpeg-extra package. You will find it in Ubuntu [universe] repo. Than you need to:
